Tear and snag-resistant, the sandbags feature reinforced, double stitching and securely hold up to 50 pounds of sand. The sandbags are easy to fill with a hemmed opening and built-in tie closures. | EASY TO STACK: A nonslip exterior eliminates the frustration of sliding sandbags when building up retaining walls. The King-A-Ma-Jigs sandbags can be easily stacked without sliding around to create flood walls, prevent seepage from hurricanes, build traffic barriers and to divert water away from buildings. | TREATED FOR UV PROTECTION: Perfect for erosion and flood control, landscaping, construction, temporary signs and fences and other outdoor uses, each reusable sandbag is treated with a UV inhibitor to withstand up to 2000 hours of direct sunlight. | SET OF 12: Each set includes 12 empty sandbags that are water, dust resistant for long-term usage. The reusable bags can be filled with sand, soil or gravel for a variety of uses.
